Definitions

  • a blanket type batch feeder for a glass melting furnace having one or more charger plates supported in such a manner that the angle of slope of the charger plate may be adjusted about an axis that substantially coincides with the lower edge of the sand seal at the rear of the supply chute. Also the charger plate may be swiveled about an axis normal to its surface to change its angle with respect to the longitudinal axis of the furnace which it feeds.
  • a mix of materials from which the glass is produced commonly referred to as the batch, or batch material
  • the batch material is introduced into one end of a melting furnace and removed as melted glass from the opposite end, and there is maintained a nearly constant level of molten glass within the furnace.
  • the batch material is first melted in a melting zone and then there is a zone of relatively quiescent flow where the newly-formed glass is fined" before it reaches the forehearth or opposite end from which the molten glass is removed for formation into a finished product, typically, flat glass, containers, or glass fiber.
  • the quality of the glass depends largely on the uniformity of the melt and the efficiency of the furnace may vary considerably with rate and manner of batch feeding.
  • the melting end of the furnace is equipped with a charging bay generally referred to as the doghouse and for use with a so-called blanket batch charge feeder there is a suspended rear wall at the charging end of the furnace that is set inwardly from the rear wall of the doghouse, leaving a kind of open or semiopen trough between the rear wall of the charging bay and the inwardly-offset suspended wall, providing a doghouse across a substantial part of the full width of the furnace, sometimes as much as 20 feet or more in a wide furnace.
  • a blanket feeder for which this invention is an improvement, has long been known in the art and is shown in U. S. Pat. No. 2,272,2l7.
  • Basically it comprises a wheeled structural frame that supports an elevated hopper, the width of which is substantially coextensive with the width, of the doghouse or trough-like furnace area into which material is fed.
  • the bottom of the hopper provides a chute that terminates over a charger plate that is reciprocated toward and away from the doghouse, its stroke being adjustable, but being of the order of a few inches, possibly notv more than minutes, but usually less.
  • This plate is supported in the frame at a level where it just clears the rear wall of the doghouse.
  • the forward edge of the charger plate has a downwardly-projecting water-cooled lip thereacross, and depending on the angle at which the plate moves with respect to the horizontal on both its forward and return strokes, it pushes against and applies vertical components of pressure to the accumulated mass of floating batch material in the doghouse.
  • the plate may slope downwardly toward the glass level in the furnace at an angle of the order of 10 to from the horizontal, but this may be more or less.
  • the present invention has for its principal object to give the furnace operator a much increased variation in the feed so as to further adjust to the idiosyncracies of a particular furnace. It provides an arrangement wherein the charger plate may slope at one angle at all times or advance at one angle and retract at another or in a horizontal plane or even be vibrated. It also provides an arrangement where with two or more charger plates each may be individually oscillated about vertical axes of rotation whereby their respective center lines at the time of discharge may converge or diverge with respect to the center line of the furnace and with respect to each other or be in parallelism.
  • both of these features are combined in a single structure, but they are not necessarily so combined.
  • the hopper is unchanged but the charger plate is mounted on a reciprocable frame which in turn is supported in such a manner on a platform that the frame and charger plate are reciprocated beneath the chute and the drive for effecting the reciprocation thereof is also mounted on this platform.
  • multiple charger plates there are preferably a multiple, two or more, such platforms side-by-side which together extend across the full width of the doghouse.
  • Each platform is hinged in a supporting frame under the hopper for'tilting abouta transverse axis to thereby change the angle of the charging plate, and the pivoting axis about which the platform tilts is directly under the rear edge of the chute so that when the angle of slope of the charging plate is changed, the vertical distance between the plate and the rear edge of the hopper remains substantially constant.
  • Means such as a fluid pressure cylinder, is provided for selectively changing the angle of the platform.
  • the charging plate should slope downward toward the furnace on its forward stroke and retract on a level plane so that the action of the depend ing water-cooled lip on the forward edge of the charging plate against the floating batch material in the doghouse will be different than if the plate reciprocates in the same plane in both directions.
  • the reciprocating motion of the plate is transmitted to the plate from a power-driven eccentric connected through linkage with the reciprocal frame or carriage structure.
  • a fluid pressure cylinder unit fixed to the frame and pivoted to the adjacent corner of the charger plate so that one cylinder ay be operated to thrust one corner of the charger plate forward while the other corner pivots on a vertical axis so that the plate may first be thrust forward, and then, while it is at its most forward limit of travel one of said fluid pressure cylinders may be operated to swivel the charger plate relative to the longitudinal axis of the furnace and thus change the angle of the forward edge of the depending water-cooled lip with respect to the accumulated batch material in the doghouse, much the same as a man with a paddle in the days of handfeeding could move some of the accumulated charge in the doghouse relative to other such material.
  • the direction of swing of the charger plate will depend on which of the two fluid pressure cylinders is activated.
  • FIG. 1 is a somewhat schematic vertical transverse section through a blanket batch charger embodying our invention wherein provision is made for changing the angle of slope of the charging plate;
  • FIG. 2 is a top plan view of FIG. 1 with the hopper removed but its discharge opening indicated in dotted lines;
  • FIG. 3 is a rear view of the charger shown in FIG. 1;
  • FIG. 4 is a fragmentary view of a portion of the rear of the apparatus shown in FIG. 3 but on a larger scale together with a schematic fluid pressure circuit;
  • FIG. 5 is a view similar to FIG. 1 where the charger may selectively provide both of the above-described options
  • FIG. 6 is a view similar to FIG. 2 embodying the arrangement of FIG. 2 together with the second option of swiveling the charger plate;
  • FIG. 7 is a view similar to FIG. 4 of the apparatus shown in FIG. 5;
  • FIG. 8 is a fragmentary vertical section through a ball support for the charging plate
  • FIG. 9 is a fragmentary transverse section on a larger scale of the sand seal and lower end of the chute.
  • the feeder has a supporting base structure 2 mounted on casters 3, as is customary with machines of this type for movement ofthe machine into and out of operating position adjacent the back wall T of the furnace tank.
  • T is the suspended rear wall of the furnace, the doghouse being designated D.
  • the charger In FIG. 1 the charger is in operating position with respect to the furnace and the charger plate is in its retracted position.
  • the supporting base structure has two upright columns 4 at each side thereof connected at their upper ends by side frame members 5 and the tops of the columns on one side are connected to the tops of the columns on the other side by a front channel section 6 and a rear angle section 7.
  • a rear angle section 7 At the base of the columns there are lower side frame members 8 and cross members 9.
  • This upright framework comprising the columns and connection sections is here shown as having a series of metal strips 10 on the base under the side frame members 8. This enables the frame to be adjusted vertically with respect to the rear wall T of the furnace tank with which the charger is used simply by increasing or decreasing the number of spacing trips 10 at each side of the upright frame.
  • the frame supports a hopper '12 with a discharge chute 13 that slopes downwardly and forwardly toward the furnace.
  • the feeder is a multiple plate feeder as here shown, there are divider plates 13a in the hopper to direct the material into the discharge openings over each plate.
  • the width of the hopper from side to side is generally the full width of the dog-house.
  • the front wall of the chute has a plurality of separately adjustable gates 14 across it, each with adjusting linkages and levers for raising and lowering them as indicated in the drawings, and which are commonly employed in the art.
  • the platform is supported on one or more extensible and contractable support assemblies, each comprising a post 20 adjustable vertically on a bracket 21 carried on the cross member 9 at the rear of the bottom of the upright frame.
  • the top of the post is pivotally connected at 22 with a fluid pressure piston and cylinder unit 23 having a piston rod 24 pivotally connected to cars 24' on the under side of the platform 15.
  • the platform may be rocked up and down between a low position determined by the initial adjustment of the post 20 in the bracket and an'upper position when the piston of the cylinder and piston unit 23 is at the upper limit of travel in the cylinder.
  • a preferred valving arrangement for operating the cylinder piston unit will be hereinafter described.
  • each side of the platform 15 there is a vertical plate 25, each of which carries a forward roller 26 and a rear roller 27.
  • These rollers provide a support for a reciprocable frame 28 having a bar 28a at each side so arranged that each bar rests on a forward roller 26 and a rear roller 27.
  • This frame has a rear cross bar 29 and a forward cross bar 30.
  • Section 31b has a lip 32 thereon which may be, but is not necessarily a hollow water-cooled nose piece.
  • the lip is located under the forward edge of plate 31b and depends from it.
  • the charger plate forms a bottom for the chute 13.
  • the front wall of the chute with the adjustable gates 14 across it terminates above the plate 31a.
  • the rear wall of the chute has a plate (see FIG. 9)33 across its lower edge, the plate having bracket members 34 on its read edge with pivots 35 on adjustable brackets 36.
  • the location of the pivots 35 with reference to the hopper plate 33 is such that the lower edge of plate 33 is biased by gravity to bear at all times on the plate section 31a.
  • the plate 33 so biased isknown as the sand seal.It tends to scrape sand on the platefree of the plate asthe plate moves on the back stroke of its reciprocal travel.
  • the bearings 41 can be adjusted vertically at the same time the posts 20 near the rear of the platform are adjusted in the same direction and the platform 15 kept level while its height above the base can be changed, and by adjusting one set of posts relative to the other, the slope of the platform '15 can be changed. It will be seen, however, that the bearing 41 provides a pivotal support that is always directly under the lower edge of the sand seal plate 33 so that when the platform does pivot, either by adjustment ofthe posts or by operation ofthe piston and cylinder unit 23, the charger plate will remain in contact with the lower edge of the sand seal because the point of contact of the sand seal with plate 31 is substantially coincident with the axis about which the platform tilts on trunnions 40.
  • Each platform 15 has an electric motor 45 suspended therefrom with a pulley 46 around which passes a belt 47 that drives a pulley 48 of a reducing gear indicated at 49.
  • This reducing gear drives a horizontal shaft 50.
  • the charger plate On its forward travel the charger plate carries a layer or blanket of batch material out from under the chute of a thickness controlled by the distance between the plate and the adjustable gates at the front of the chute. When the charger plate retracts this material is crowded or pushed off into the dog-house over which the charger plate projects. Therefore the length of the stroke controls the amount of material charged into the furnace on each stroke.
  • the charger plate will move forward at a fairly steep angle, then be lowered at the forward limit of its travel to a generally level or'horizontal'position and retracted to be raised again the platform '15, making it unnecessary to change the position of the sand seal each time the angle of the charger plate is changed.
  • the relation of the charger plate with respect to adjustable gates at the forward edge of the chute does change with a change in slope of the platform and charger plate but this poses no problem since the change usually takes place when the charger plate is at one limit or the other of its travel or adjustment of the gates may quickly be made to compensate for any increase or decrease in the amount of batch material because of a change of angle at some particular time in the cycle.
  • our invention further contemplates that the charger plates may be swiveled about an axis normal to the plane of the charger plate, preferably in conjunction with the above-described arrangement or separately therefrom.
  • This phase of our invention is hereinafter described in detail as a further modification of the structure above described but may be embodied in a conventional blanket type feeder whether it has the tilting platform arrangement here described or not.
  • the reciprocable frame 60 corresponds to the reciprocable frame 28 of the construction first described and it is reciprocated in the same manner by two adjustable cranks 62, one at each end of shaft 63 and adjustable links 64, that connect the cranks with rear frame bar 65.
  • This shaft extends from each side of a centrally positioned gear box 66 and there is a driving motor 67 transmitting power to the gear box through a belt or chain 68.
  • the platform in this case has a roller 15 near its forward end on which the front or lower end of the reciprocable frame 60 is supported for back and forth travel. This roller replaces the rollers 26 and 27 in the form previously described.
  • the composite charger plate is designated 71 and it has a cross bar 72 of angle section at its rear end.
  • the cross bar 72 has a slotted extension 73 thereon that rests on the extension 70 of the reciprocable frame and a roller 74 on the extension 70 has a working fit in slot 75 of the extension 73.
  • the cross bar 72 of the charger plate assembly also has a lug 76 thereon above its extension 73 at each end of the bar 72.
  • a clevis 77 is pivotally connected at 78 with this lug.
  • the clevis 77 is on the end of a piston rod 79 having a piston (not shown) in a fluid pressure cylinder 80.
  • the end of the cylinder 80 opposite the one from which the piston rod extends is pivotally anchored at 81 to a bracket 82 on the rear end of the frame extension 70.
  • one rear corner of the charger plate can be pulled backward, relatively to the other and thereby oscillate the charger plate about one pivot 78 or the other on an axis normal to the surface of the charger plate, and thereby position the water-cooled lip 84 at the forward end of the charger plate diagonally with respect to the dog-house, as indicated in FIG. 6.
  • the water-cooled nose may be oscillated over the dog-house.
  • balls 85 in retaining sockets 86 on the front and the underside of the charger plate has a bearing plate 87 fixed thereto, one of them being positioned to ride on each ball. It is contemplated that the balls 85 be made of dense carbon to withstand the high temperature over the dog-house and adjacent thereto and still rotate freely. Usually the arc of movement of the charger plate will not exceed about l0 each side of a centered position, but the exact range may be adjusted as further research with differtion with FIG. 4.
  • a selector valve 94 such as a two-way valve which may be either manually or automatically operated to effect the operation of either one of the cylinders while the other is held inactive.
  • a remote control for all functions where there are multiple plates that operate moreor less sequentially, similar to remote control timers now used with multiple plate feeders.
  • the invention provides a method of an apparatus for feeding batch materials from a hopper wherein the slope of the charger plate may be changed without changing the relation between the charger plate and the sand seal. Further, it selectively enables the slope of the charger plate to be changed during operation and even during each cycle of operation. In addition or alternatively, it provides an arrangement wherein each charger plate may swivel relatively to the dog-house either toward or away from the center line of the machine or even alternately. While accomplishing these functions, it does in some respects simplify the overall construction of the feeder especially by mounting the charger plate and its drives and plate operating means all on the same supporting platform.
